    Default First-timer build--- probably farely noob question

    Hello hello hello

    I'm building my first saber with sound.

    Basic Parts list:
    Using a Nano Biscotte (V3).
    Tri-cree XP-E2 RGRB
    I've done the calculations and checked online and watched the videos.
    My results and the videos and the online calculators don't quite line up.
    I have calculated that I need
    Red Die: 1.2Ω 1.2W Resistor. (?)
    Green Die: 0.11Ω 0.11W Resistor. (Rounded as suggested to a 0.5Ω 1W)
    Royal Blue Die: 0.29Ω 0.29W Resistor. (Rounded as suggested to a 0.5Ω 1W)

    My problem comes in at the Red Die
    Some calculators on the net say 1W is sufficient for this resistor, the information I have for the Wattage of a resistor is the higher the better (usually aim for Double calculated Wattage).
    I saw Tim used a 3W resistor for his red Die in the video tutorial on wiring a FoC using the NB v3.

    What I the overall consensus of this, is a 1W sufficient or should I look for a 3W?
    I would I can Buy for TCSS but the shipping is hell as I live in Japan

    P.S if this is in the wrong place of done incorrectly, I apologize, I'm new to most of this and will happily correct my error

    I never round wattage down. I'd bump the Red resistor up to a 2W minimum. would work nicely.

    The Green and Royal Blue would be quite happy with this one: There's no need to bump that wattage past 0.5W, though it won't hurt anything if you do.

    Wattage is a minimum. Never go lower. You can always go higher, but be warned that large wattage resistors can get BIG in a hurry and eat up your internal saber space.
    We all have to start somewhere. The journey is all the more impressive by our humble beginnings. for the lazy man's resistor calculator! for getting resistor values the right way!
